ing brackets 9, it has both longitudinal and tiltable adjustment. e

As previously stated, a feature of our nvention is a longitudinal andtiltable adjust- Vlongitudinal adjustment of the mold board within itslimits, and said bracket pairs each Via being'fad'ap'ted to readilyremovably support an adjusting screw l2O. vThis adjusting screw 2O ispreferably pivotally held at its head by a shaft 2l which passes*throught-he, L brackets 16-17 and suitably held therein as by a cotterpin 22. This screw 20 then passes through the veye of a stud 23 which ispivoth'allyhel'd-in they Vbracket -9 as vindicated yat the sectionalportion-in Fig. 4, so as to allow swinging of the screw 2O when theinol'd board is pivotally adjustedby'th'e nuts 24,

and also to allow swinging each bolt 2O from Yone positionto the otherto engage the proper bracket pair 16-17 or 18-19 Ywithout adju'stmentwhen the mold board is reversedV or swung from one facingv position toanother indicated by the 'dotted linepositions in Fig. 3. The locknuts24 are threaded upon 'the screw 2O so as to lock'it andthemold board in'anytilte'd position. TnFig. 3 the full lines show the mold boardl in avertical position and' the dotted lines to the left in- -d-icatethemoldboard tilted` slightly into one *of its angular adjustments.

f- As previously stated, the adjusting screw is adapted forinterchangeable 'support in "any "of 'the paired brackets 16s-17, or in18-1`95wh-en lthe mold board isreverSed, and

'in the embodiment Vofour inventionlillustrat-ed we show i'ive bracketpairs, thus permittingl `five points longitudinalv adjustment. This yis.sufficient for ordinary :operating conditions, Aalthough it will beapparent that the number ofpositions may fbe increased or deycreasedwithin the `limitsof Adesired loIrg-i- Ythe moldboard, or rather fromtheextrenie end bracket pair as 16-1'7 at one endl to `the extremebracket pair yat the other end, J

' thusA also' serving as'a brace to strengthen the finold'v i' boardlongitudinally.' These bracl'rets'ar'e riveted by both angles into theangle of the V"bar 25 and thus the brackets and bar25'strengthen'eachother. I

' .In*ordertopositively 4lock the mold board in anyo itslongi'tudinalilyE adjusted positions and prevent shifting thereof by theeirtreme pressure placed thereon duri-ng operation, we have yprovid-edla novel `construction permitting positive interlocking of the bracketsand mold board in its diierent 1ongitudinal positions. To this endinterengaging or abutting elements on the mold board and suspendingbrackets 9 are supplied. Thus each main supporting bracket 9 is providedat its lower end with a lug as 2G adapted to enter the proper slot as 27in a bar 28 secured to the rear face of the mold board, preferably bybeing riveted thereto. Vlith theinold board adjusted at'one eXtremeposition, as indicated in F ig. 4, the adjusting screw 2O is in thefirst bracket pair 16- 17 in which case the lug 26has entered the ifirstslot 27. VJ ith the mold board' adjusted to the second position, thescrew`20 would of cou-rse be vrinthe second pair of brackets 16-17 andthe lug 26 would enter the second slot 27, and so on, depending upon thepoint of longitudinal adjustment. j

it will be 'noted that the main supporting '.'bracl-ret hasfanoppositely extending lug 2G", this being provided for cooperation withthe mold board when itis moved to Ja .reversed or oppositely facingposition as indicated by the dotted linesto vthefrightin Fig. .3. y

Assuming that Vthe info-ldboard-is to be reversed, that is', 1moved tothe opposite side of the brackets 19;,.the- -adjustin'g screw 2O lisreleased irom-the mold boar-d and this may be done by withdrawingftheCotter pin2-2i from thefpin-21of eachadj-usting screw, permitthis pin 21to'beffwithdrawnfrsdas to vtree the'lm'old board. A The inold board maythe brackets" 9 as indicated by the lower dotted line positionl of Fig.3, and -then Amoved Vup-into :position on the opposite sident thebrackets.` This will bringa lower 4bracket pair 18-1'9 up'tor'engagement with reach adjusting screw 20, Landlthere'fore thehead A ofvthe screw 'is `permitted -to enter Abetween 'the proper bracket pair18-19 andthe pin 21 inserted. This operation, of course, per-Aformed-"iat eachloneof the two .supportingv brackets 9 and niaybefinade without any ad justinent of the screws 20. The mold board maythen be tilltably adjusted toV any `desired position by manipulating the`lock nuts 9A at each of two adjustingnscrewvs 20. As the. mclld vfboardis swungroinloire position to the other, the lili-gz26 enters theappropriate slot 27 in the bar 28 on 'the rear tace of Sthe'mold board.,-so :as to flock it againstlon- 'giitudinal shifting;y

v`we haveprovlidedan vimproved nndersiung 'double reversible lm'ol-dboard which maybe reversed'so' as to. face in either ydirection 'fromwhich the` info'ldfboarcl may betiltably fardju'sted/ in either: 'et itstwo ia/cingv posi-tions 'in which longitudinal zad'justinentiils' :per-.antte'd but interlocking means arev provided* 4nis for positivelyholding the mold board against longitudinal shifting during operation;and a symmetrical mold board for vthe above construction having doubleremovable cutting edges or blades whereby the mold board may-V bereversed intoeither of two opposite operating positions and held inidentical adjustment in each position.

There are other advantages in construction and in operation, dependingto some eX- tent upon the method of applying the mold board andsuspending brackets. tothe circle frame or other holding means, and wecontemplate constructing and using our invention in other ways thanherein shown and v therefore do not desire to be limited to the exactarrangement illustrated andk described,

but aim to cover all that which comes with-Y in the spirit and scope ofthe appended claims. What We claim as new and desire to secure by UnitedStates yLetters Patent is l.
